【正文】 e decision in some aspects. Large machinery is difficult to popularize, so need to popularize some small household machinery. Corn threshing machine which is a very typical example, along with the people of the maize yield increase, corn threshing became a priority in an issue that people first, manual threshing too slow, timeconsuming, and requires a lot of people, very inconvenient, corn threshing machine, to solve the a problem, need less labor, and is mainly the work efficiency is greatly improved, so the corn thresher is essential for an agricultural farm. The corn thresher is corn peeling, after drying for a period of time, then the use of corn thresher for corn and corn cob separately, this machine is the corn threshing machine. Its working principle is: corn thresher for corn threshing, the gap between tooth and nail screen tooth cylinder rotary motion of the match, the corn grain down (between the nail tooth roller and a screen kneading action, the corn grain from corn cob, I Suke and other mechanical corn and corn cob respectively from two different outlet outside a machine body, separated by the sieve grain, corn cob discharging machine tail, from corn silk, dander from outlet. Circular threshing, the threshing fill discharge the body of the loop. This kind of machine, the threshing efficiency by the drum length and diameter is determined according to the threshing efficiency, people can own, corn thresher, the reasonable selection of appropriate.Key wordcorn sheller；Threshing structure；design 目 錄1. 引言……………………………………………… 32. 玉米脫粒機(jī)的總體結(jié)構(gòu)的設(shè)計(jì)………………… 5 …………………… 5 ……………………… 63. 電動(dòng)機(jī)的選擇………………………………………7 ………………………………… 7 ……………………… 7 ………………………………… 8 ………………8 ……………………8 ……………………104. 帶及帶輪的設(shè)計(jì)……………………………………11 ………………………………… 12 ……………………………12 …………………………12 ……………………12 …13 ……………13 ……………………13 …………………………14 ………14 ………10…………………………………15 ……………………………… 15 ……………………………… 15 ……………………15 …………………………15 ………………………………………16 ………………… 18 …………………………… 18 ………………… 19 ……………………… 19 ………………………………… 227. 校核軸承的強(qiáng)度…………………………………… 238. 滾筒的設(shè)計(jì)………………………………………… 239. 釘齒的設(shè)計(jì)………………………………………… 2510. 篩網(wǎng)的設(shè)計(jì)…………………………………………2511. 入料口及脫粒上蓋的設(shè)計(jì)…………………………2612. 除塵裝置的設(shè)計(jì)……………………………………2813. 機(jī)架的設(shè)計(jì)…………………………………………2914. 軸承座的設(shè)計(jì)………………………………………3015. 玉米脫粒機(jī)上標(biāo)準(zhǔn)件的選擇………………………31 ……………………31 ………………………………………3116. 玉米脫粒機(jī)的使用和維護(hù)…………………………31 ……………………31 ……………………32結(jié)論………………………………………………………33致謝………………………………………………………33參考文獻(xiàn)…………………………………………………341引言隨著社會(huì)的進(jìn)步，農(nóng)業(yè)機(jī)械化已經(jīng)在我國(guó)普及開(kāi)來(lái)，特別是一些家用的小型機(jī)械也進(jìn)入千家萬(wàn)戶之中。s of last century, China39。循環(huán)脫粒，不斷的進(jìn)行填入—脫?！懦鰴C(jī)體這一循環(huán)。 隨著社會(huì)的發(fā)展，機(jī)械化在我國(guó)普及的速度很快，由于我國(guó)是農(nóng)業(yè)大國(guó)而且農(nóng)業(yè)是我國(guó)的經(jīng)濟(jì)基礎(chǔ)，所以普及機(jī)械化對(duì)于我過(guò)農(nóng)業(yè)的發(fā)展是至關(guān)重要的，但是由于我國(guó)的農(nóng)業(yè)現(xiàn)狀，大都屬于小農(nóng)經(jīng)濟(jì)，所以決定了在某些方面大型的機(jī)械很難普及，所以需要普及一些小型的家用機(jī)械。1815年, 美國(guó)開(kāi)發(fā)出世界上第一臺(tái)專用于玉米脫粒的手工操作玉米脫粒機(jī)。之后人們對(duì)于玉米脫粒裝置的改進(jìn)一直沒(méi)有停止過(guò)。玉米脫粒機(jī)就是其中一個(gè)很典型的實(shí)例，隨著人們的玉米產(chǎn)量的不斷增加，玉米脫粒就成為了一個(gè)擺在人們而前的一個(gè)問(wèn)題，人工脫粒太慢，費(fèi)時(shí)間，而且需要的人很多，很不方便，玉米脫粒機(jī)的出現(xiàn)，解決了這一問(wèn)題，需要的人工少，而且主要是工作效率有大大的提高，所以玉米脫粒機(jī)是農(nóng)家不可缺少的必備農(nóng)機(jī)。該種機(jī)器，脫粒的效率由滾筒的長(zhǎng)度和直徑而確定，人們可根據(jù)自己的脫粒效率，合理的選用適當(dāng)?shù)挠衩酌摿C(jī)。s selfdeveloped impact principle of corn threshing machine is widely used in large, medium, when threshing machine. After entering 80 age, rural began to implement the household contract responsibility system, our country has developed a series of impact principle, small corn thresher, in order to meet the production needs of farmers. With the development of society, the mechanization in China spread very quickly, because China is a big agricultural country and agriculture is the economic foundation of our country, so the application of mechanized is crucial for the develo
